This interactive scatter plot displays automobile data from the UCI Machine Learning Repository's Auto MPG dataset. Users select which columns to plot on the X and Y axes via dropdown menus. The visualization uses D3 v5, with `scaleLinear` for scales, `extent` for domains, and `axisLeft`/`axisBottom` for rendering axes. Each data point is an SVG circle that transitions from the center to its position over 2 seconds using `transition().duration(2000)`. Axis labels update to reflect the selected columns.
